Thanks for the reply guys, did some testing today for about 7 hours and it did not leak. Gonna try it out in the full loop tomorrow.

Yes, the Purple place. O ring is not damaged.

Well, its a custom loop. As i Said in a Previous post its a loop containing blocks for both cpu and gpu plus the 420 rad.

The pump+res is an EK-XRES 140 Revo D5 PWM

Not sure if you're calling me stupid, this doesn't really help me tho. I can't really explain more because there's nothing else to explain about the leak other than it's the connection between pump and res and the top lid of the res was nearly impossible to open. If you're gonna argue please continue somewhere else. ?

Maybe i should have mentioned this, but its a loop for gpu/cpu With a 420 rad in the front

I mainly drained to see if the o ring was damaged, i already know where the leak is coming from and thats the only place, what i dont know is why its leaking from that spot and how.

Thanks for the Quick reply! The thing is, theres no leaking from fittings at all, its only through the connection between the res and the pump. ?

Ive had my loop for a few months now, nothing leaked. But now suddenly it started leaking between My res pump combo, i dont wanna say i did a proper leak test, only did for about 1-2hrs first time. I did drain the loop now to check o ring between res and pump, my only idea is that its a Long built Up pressure? Because of air.
